The common types of damage in sandwich panels during normal use include: core seam damage, delamination caused by adhesive aging due to alternating hot and cold temperatures, and indentation damage caused by impact. Such damages can weaken the load-bearing capacity of sandwich panels. If not identified promptly, they may result in accidents and potential injuries. In this study, a non-metallic ultrasonic testing device was used to detect various types of damage in the sandwich panels, and wavelet analysis theory was applied to process the experimental data.
